Abstract By using the Corey diamine 1, 2-diphenyl-N, N′-bis [(2, 4, 6-trimethylphenyl) methyl]-1, 2-diaminoethane, Copper (I) olefin complexes are prepared. When the olefin is a racemic allylic alcohol, selective coordination of one enantiomer is observed. Cleavage with aqueous HCl or NaCN allows a two-steps resolution affording excellent enantiomeric excess.
